Ah, apparently some minister in Germany proposed ticket gates on railway stations. Let me give you a list of railway stations in the Netherlands that have been rebuilt or are currently being rebuilt to fit in ticket gates: Den Haag Centraal, Den Haag HS, Delft, Amsterdam Zuid, Amsterdam Centraal, Amsterdam Bijlmer ArenA, Utrecht Centraal, Rotterdam Centraal, Breda, Tilburg, Eindhoven Centraal, Arnhem Centraal, Groningen, Zwolle. You can't just deliver a couple of ticket gates to a station, you completely need to rethink transfer capacity. What happens when a train delivers 600 passengers at once in your station? You need to rethink routing, you can't have an escalator spitting out passengers close to ticket gates. How do you separate train passengers from passengers going to the bus/tram/metro stop or use the station as a connection between city quarters? If you really want this, you have to spend a lot of money and completely start redesigning and rebuilding stations. Somehow I think the German railways should have other priorities at this moment.
